Maximum Frequency
In a third step, the inverter tests the maximum frequency.
During the test sequence, the frequency limit applied is
shown in the display of the inverter.
The frequency limit is reduced successively until the
disconnection threshold is reached and the inverter
disconnects from the mains.
Once the inverter has disconnected from the mains, the display successively shows the following
values one after the other:
• Disconnection value,
• Calibration value,
• Reaction time,
• Current power frequency.
